The problem isn't jobs, it's wealth creation. The federal government could easily give everyone a job, bringing unemployment to zero. That would require either massively devaluing the dollar, or taking more than half what we earn in taxes. Either way our standard of living would plummet.
What we need to concentrate on is wealth production - how we maximize manufacturing, mining, farming, fishing. There are easy answers there too, but not without significant negatives. Removing environmental and safety regulations & laws and removing red tape would bring back a lot of manufacturing and mining jobs, at the expense of widespread pollution and injured workers. Removing environmental regulations and laws on fertilizers, pesticides and herbicides would make our farming more competitive, at the expense of widespread pollution and species driven to extinction, and lowered public health. Eliminating limits, seasons, sanctuaries and illegal methods would be a boon to fishing, but would soon destroy stocks, driving some species extinct and seriously unbalancing marine ecosystems. There are no easy answers.
Personally I thing we're going to have to go back to import tariffs as the main method of funding government, which will allow us to artificially make foreign products as expensive (or more so) than American-made products. We're also going to have to decouple health insurance from employment - I prefer individual health savings accounts, but it will probably be through government-rationed health care. And I'd like to see the corporate income tax abolished and replaced with a national sales tax like the FairTax, which would force foreign manufacturers to bear at least the same effective tax rate as domestic manufacturers. Unfortunately things like wealth envy will prevent most of these things from happening. Too many people find punishing the rich much more important than saving domestic manufacturing.
